Learn about Samil Power SolarRock Error Code 122, its meaning, causes, and solutions for isolation faults.
Error Code 122 indicates an isolation fault in the Samil Power SolarRock inverter. This can affect the system's performance and safety.
To troubleshoot Error Code 122, check the inverter's isolation resistance and ensure all connections are secure. If issues persist, consult a technician.
The Samil Power SolarRock inverter triggers fault 122 as a protective measure when it detects an insulation fault within the system. This typically occurs when the insulation resistance (RISO) measurement falls below the acceptable threshold, indicating that current may be leaking to the ground. Ground fault detection is a critical safety feature designed to prevent potential hazards such as electric shock or fire. The inverter continuously monitors the DC circuit, and if it senses an imbalance caused by leakage current, it will shut down to protect both the system and the user. Furthermore, external factors such as moisture or corrosion can exacerbate insulation failures, leading to this fault.
Homeowners may notice the inverter's LED indicator flashing a specific pattern associated with fault 122. Additionally, monitoring apps may alert users to a drop in energy production, often showing zero output from the inverter despite sunlight conditions. The system may also experience intermittent shutdowns or failures to start.
Always consult a licensed electrician or certified solar installer when dealing with electrical faults. Working on live systems can pose serious safety risks.
To avoid future occurrences of fault 122, ensure regular maintenance of the solar array, including inspections for wear and tear on cables and connections. Implement protective measures against moisture ingress, such as using weatherproof junction boxes. Regularly update the inverter's firmware and maintain proper system practices to minimize the risk of wiring errors.
